Zusammenfassung:Systems and methods for 3D audio programming and processing are provided wherein digital signal processing (DSP) settings are calculated for 3D audio effects for a digital audio signal independently of DSP rendering of the digital audio signal. Coordinates of locations within a 3D environment representing at least one sound source and at least one audio listener are created and passed (along with other distance modeling parameters) to a DSP settings generators having 3D audio library routines to calculate the DSP settings for 3D audio effects based on the distance between the at least one sound source and at least one audio listener and the distance modeling parameters. Support for positional multi-channel sounds and non point-source emitters is also present.
